The Effects Of Sewage Pollution Abatement On Phytoplankton Productivity And Standing Crop In Hillsborough Bay, Florida, City Of Tampa Department Of Sanitary Sewers

Reports

In September 1976, the City of Tampa initiated a comprehensive monitoring study of the ecology of the phytoplankton community of Hillsborough Bay. Numerous studies elsewhere have shown that phytoplankton are well suited as monitors of trophic state due to their rapid response to changing environmental conditions (Hohn, 1959; Williams, 1964; Margalef, 1968; Welch, 1968; Dunstan, 1975; Taslakain and Hardy, 1976). The present study is designed to relate changes in the phytoplankton community of Hillsborough Bay with the reduced nutrient load entering the Bay from the AWT facility.

Acute Biological Effects Of Chemically Dispersed Oil Spillage : Final Report To The American Petroleum Institute, George C. Grant, Howard I. Kator, Paul L. Zubkoff

Reports

Primary productivity, heterotrophic potential, chlorophyll i! and phaeophytin, ATP, and direct bacterial counts were measured in the sea surface layer under controlled spills of La Rosa and Murban crude oils following immediate dispersal with the EXXON dispersant, Corexit 9527. Tests were conducted off New York on November 9, 1978.

The response of productivity to dispersed oil appeared as an initial increase in rates, a reduction to minimal rates 1-2 hours after dispersion, and a return to pre-spill rates after 3 hours. Comparison of productivity measurements from the two tests suggested a more efficient and rapid dispersion of the somewhat lighter …

A Survey Of The Late Summer Benthos Community In The Vicinity Of The C. P. Crane Generating Station, Robert A. Jordan, Charles E. Sutton, Patrica A. Goodwin

Reports

A survey of the sediment distribution in the vicinity of the C. P. Crane Generating Station, Bengies, Maryland showed that the sediments in the creeks receiving the plant's cooling water discharge were predominantly soft clayey-silt. The benthic invertebrate taxa found in these sediments were typical of the connnunities found in oligohaline waters of Chesapeake Bay. Comparisons of the benthic community in the discharge area with the connnunities in two reference areas of similar sediment type revealed an apparent reduction in the discharge area population of the dominant amphipod, Leptocheirus plumulosus, in August.

An Environmental Assessment Of The Summer Plankton In The Vicinity Of The C.P. Crane Generating Station, George C. Grant, Stephen P. Berkowitz

Reports

A preliminary survey of summer plankton in ·waters surrounding the C. P. Crane generating station in Bengies, Maryland, revealed several possible effects of plant operation. These perturbations were separated into apparent small-scale and large-scale effects:

Small-scale effects were limited to the immediate discharge region of Saltpeter Creek and included (1) occasional elevation of temperatures at the surface (in August) to above the lethal limit for most zooplankton and sufficiently high to inhibit photosynthesis, (2) a decrease in chlorophyll-a, seen in July and August, (3) a sharp decrease in productivity, also in July and August, and (4) absence of a common …
